Abstract

PURPOSE: To reduce a coloring component, COD, an oil component to a draining standard value or less by a method wherein a metal ion is added to the waste liquid and, thereafter, the pH thereof is adjusted to almost 7 by a caustic alkali to remove a generated precipitate and, moreover, the filtrate thereof is treated by activated carbon.
CONSTITUTION: To the waste color check liquid, a metal salt solution for forming a precipitate in a pH range of a draining standard, for example, an iron salt solution is added and the pH thereof is adjusted to almost 7 by a caustic alkali to coprecipitate the coloring component, the COD component and the oil component in the waste liquid. Subsequently, the filtrate obtained by removing the precipitate is treated by the activated carbon to adsorb a small amount of the residual aforementioned impurities to reduce said impurities moreover.
